TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 627,762, dated June 27, 1899.

Application filed August 22, 1898.

T0 all whom zit may concern:

Be it known that I, CHARLES K. RosnN- BERG, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Ternporary Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to a certain new and useful temporary binder or file-book for use more especially in connection with what are known asremovable-leafledgers oraccount books; and it consists in the arrangement of parts anddetails of construction, as will be hereinafter fully set forth in the drawings and described and pointed out in the specification. 1

The invention mainly resides in the peculiar form of lock mechanism employed for locking the removable cover of thebinding to the supporting or file posts; and the object is to simplify the lock mechanism and protect the same against injury or accidental damage due to rough usage of the file or binder,while at the same time providing for the positive locking and holding of the parts at any do- In order to comprehend the invention, reference must be had to the accompanying sheet of drawings, forming a part of this application, wherein Figure 1 isa perspective view of the binder or file-book when closed and partlyfilled with leaves. Fig. 2 is a detail view of the frameplates and file-post, the upper or adjustable frame-plate being partly in section. Fig. 3 is a top plan View of the upper or adjustable frame-plate, the same being partly broken away so as to illustrate the position of the slide lock-plates; and Fig. 4 is a detail View of the operating-key.

In the drawings the letters A A are used to indicate the top and bottom covers for the book, which in the present case are connected to suitable stubs by means of a flexible joint a. This form of flexible-joint connection is made use of in order that the covers may be opened so as to permit the retained or fixed leaves B to be examined the same as in an ordinary book-that is,without the necessity of the upper cover being unlocked and moved gerial No. 689,203. on model.)

upward upon the leaf supporting or file posts. The stub of the bottom cover consists of a frame-plate B,which is fastened to the cover A by the binding A thereof, as shown in Fig. 1 of the drawings, and to this plate is rigidly secured the upwardly-extending supporting Y or file posts for the leaves, preferably consisting of a series of sections 1 2 3, which are removably connected by one screwingonto the other. Upon these supporting or file rods works the upper adjustable frame constituting the stub of cover A, which in the present case consists of two plates B B held a distance apart by means of the slide lock bars or plates 0 O. Theupper adjustable frame-plate is attached to the cover A by means of its binding-cover A The plates B B of the upper adjustable frame are connected by means of the screws 4, which screws pass through longitudinal slots 5, cut in each slide lock bar or plate 0 0, so that said bars or plates may be free to have a limited longitudinal movement toward or from the supporting or file posts. These posts extend through circular openings 6, formed in the upper frame-plates, and elliptical slots or openings 7, cut in the slide lock bars or plates 0 C.

The elliptical slots 7 form, in effect, oppositely inclined or converging faces 7 which when the lock-plates are moved longitudinally outward or away from each other cause the posts 3 to wedge in between them and Without any strain whatever on the surrounding or inclosing parts firmly and positively hold the frame in the adjusted positions on the posts.

V The inner end of each slide lock bar or plate is reduced, so as to permit of movement alongside of each other and each reduced end portion is provided with a key-seat 8, which fall below the circular key-opening 9 formed in plate 13 of the upper adjustable frame. Through this key-opening fitsthe key 0 the lugs 10 of which pass into the key-seats 8.

Presuming the parts to be locked and it is desired to release or remove the cover A in order to insert or file a new leaf or leaves, the key is first fitted so as to place the lugs 10 in key-seats 8 of the slide lock bars or plates 0 C. The operator then turns the key so as to draw the slide lock bars or plates inward their full distance, Fig. 3 of the drawings, when the outer end portions will be released from frictional engagement with the supporting or file posts, when the adjustable frame-plate constituting the stub ofcoverA is,free to be moved up or down or be removed from the supporting or file posts. To look the adjustable frame, it is only necessary to give an opposite turn to the key when the slide lock bars or plates will be thrown outward and frictionally engage the supporting or file posts, as hereinbefore mentioned. The frame-plate will remain thus locked and the papers or leaves firmly held between the covers until the said frame is unlocked, as above described.

Bymaking the supporting or file post jointed 0r extensible the same may be readily lengthened or shortened in order to increase or decrease the holding capacity of the filebook.

While the present book-binder is mainly designed as a temporary binder to be used in conjunction with removable-leaf ledger-s or account-books, I do not wish to be understood as confining myself to such use, as I am Well aware that it may be used as a letter, bill, or receipt file.

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent, is-

1. In a temporary binder or file, the combination with the covers, of a frame-platecarried by one cover and serving as a stub therefor, supporting or file posts secured thereto, a frame-plate secured to and carried by the opposite cover and adapted to slide upon the supporting or file posts, slide lock-plates carfaces between which the posts extend and between which the posts wedge when the lockplates are moved longitudinally,substantially as described.

2. In a temporary hinder or file, the combination with the supporting or file posts, of a frame-plate with which the same are secured, an adjustable frame-plate sliding on said sup= porting or file posts, longitudinally-movable lock-plates carried by the adjustable frameplate, and each provided with oppositely in clined or converging faces between which the posts extend and between which the posts wedge when the lock-plates are moved longitudinally, substantially as described.

3. In a temporary binder or file, the combination with the supporting or file posts, of a frame-plate to which the same are secured, an adjustable frame-plate sliding on said supporting or file posts, longitudinally-movable lock-plates carried by the adjustable frameplates, each provided with key-seats in the adjacent ends thereof, and each provided with elongated holes having oppositely inclined or converging faces between which the posts extend and between which the posts wedge when the lock-plates are moved longitudinally, substantially as described.

In testimony whereof I aflix my signature, in presence of two Witnesses, this 16th day of August, 1898.

CHARLES K. ROSENBERG.
